"I do not know what may be the extent of the claims you are advancing in regard to the benefits accruing from the practice of your principles. If you, as you in justice may, claim even the widest benefits as surely following the practice of these principles, many will relegate these claims to the limbo where all such 'panaceas' are soon forgotten. They will err greatly if they do so. The seemingly simple procedure of insalivating one's food most carefully is not calculated to impress people with the fact that great permanent benefit follows. The subtlety of the changes that occur is due to the greatly increased action of a vital process, _i. e._, of the admixture with the food-stuffs of saliva, in such quantities as to alter the chemical reaction of the initial stage of digestion. This initial change causes a consequent change of all the processes following it, and a change also in the final products of the entire process of digestion; the greatest change being, perhaps, the elimination of last-resort digestion by the intestinal flora (digestion by decomposition caused by bacteria), and consequent elimination from the body, of the toxins they produce. The life of an organism has been defined as 'the sum of all those inter-actions which take place between the various cells constituting the organism and their several environments.' (Harry Campbell.) The final products of digestion are absorbed into the blood stream, and go to form part of the 'several environments' of the cells. The individual cell, the various groups of specialised cells, such as the brain, nerves, muscles, bones, etc., in short, the whole organism is beneficially influenced and made more resistent to disease by the purity of a blood stream that no longer contains the toxins of bacterially digested food. "The further investigation of your discovery by those competent will, I am confident, result in such a simplification of the rules for a healthy life that the medical profession, at present forced by a lack of knowledge of the vital processes of nutrition to base their treatment on the veriest empiricism, will then be able to teach all and sundry how to live. At present, all we can do is to treat and perchance cure for a time certain symptoms, allowing the patient to return afterwards to a mode of life that is really responsible for his malady. 'Disease is an abnormal mode of life.' (Harry Campbell.) The three factors in its causation are: "(_a_) Cell structure. "(_b_) Internal cell environment. "(_c_) External body environment. "Heredity determines, to a very large extent, our cell structure, and consequently our body structure. "Sanitary science regulates our external body environment as much as the artificial and noxious habits of so-called civilisation will allow. The mental and physical external body environments have also their effect on the organism.
